At Thomson Lamination Company (TLC), we are a premier manufacturer of stamped motor lamination components. We can produce prototypes to high-volume production quantities of rotor and stator laminations from high-conductivity metals to tight tolerances.
What Are Motor Laminations?
Motor laminations form the core of an electric motor’s stator and rotor. They consist of thin metal sheets that are stacked, welded, or bonded together. By making them from individual pieces of metal rather than a solid pieces, they experience less eddy current losses.
Our Motor Lamination Materials
Our motor lamination experience allows us to use a variety of materials to stamp out motor laminations, such as:

Our 76,000 sq. ft. facility houses a variety of high-speed presses with capacities of up to 250 tons and the capability of running dies up to 36 inches by 72 inches in size as well as an extensive catalog of over 1,500 dies. This equipment enables us to stamp motor laminations in the full round from 0.5 inches OD to 15 inches OD for use in core assemblies. If the customer has highly specific or unique requirements and restrictions, we can design and build proprietary dies that suit their exact needs, whether the project calls for dedicated carbide progressive dies or master insert dies.
In addition to our metal stamping capabilities, we also offer in-house annealing, grinding, assembly, and other post-stamping services to ensure we can deliver complete motor lamination fabrication solutions. Once the thin lamination sheets are stamped, we stack them by bonding, welding, riveting, or staking them in the die to form core assemblies. After the completion of the project, we store each die physically and digitally to ensure we can quickly manufacture more pieces when they are needed.
Your Product. Our Precision. That’s TLC.
Whether you need standard or unique motor laminations, TLC can handle your requirements. Our 57+ years of experience and equipment enable us to accommodate nearly any custom request, whether you need a particular die design, a specific material, special annealing requirements, or precise tolerances. That’s why customers across a wide range of industries—aerospace, energy, machine tool, medical, and military—know they can trust us to deliver motor laminations that meet their specifications and quality standards.
